About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX275-100S
The AirTAC SAIJ200X275-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a 175 to 275 mm usable travel window. Built with a 200 mm bore, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, scaling to a maximum of 3204 kgf at 1.0 MPa. This specific SKU includes a SUS420J2 stainless steel rod (material code A) and a PT tapered port thread.
Because the adjustment range is up to 100 mm, operators can dial in the exact retract position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX275-100S Is Used
Heavy Press Tonnage Tuning
Dial in the exact 175-275 mm retract stop on heavy press machinery to accommodate different die heights without physically swapping cylinders.
Automated Assembly Changeover
Adjust the end-stop position during product family changeovers on large automated assembly lines, utilizing the 3204 kgf maximum force for robust actuation.
Large Fixture Positioning
Fine-tune the clamping travel of massive pneumatic fixtures, relying on the SUS420J2 stainless steel rod for corrosion resistance in demanding environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX275-100S the Right Cylinder?
Select this 200 mm bore adjustable-stroke cylinder when an application requires immense thrust combined with variable end-position tuning across a 175-275 mm window. If the 15708 N push force at 0.5 MPa exceeds your actual payload requirements, stepping down to a 160 mm bore yields 10053 N, optimizing air consumption. Conversely, if you need less travel fine-tuning, a smaller adjustment code like -50 mm provides a tighter setup window.
When matching this ISO 15552 replacement, verify the 275 mm stroke, 100 mm adjustment, PT port thread, and the -S magnet option. Note that the rear adjuster functions strictly as a mechanical travel stop to set deceleration endpoints; it does not hold the load without live air pressure. For fail-safe load holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. Furthermore, at a 275 mm stroke on a 200 mm bore, the M36x2 rod thread and 40 mm rod diameter handle high axial loads, but an external guide rail is recommended to manage side-loading moments.

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200AX275-100S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum operating pressure of 1.0 MPa, it delivers a peak push force of 31416 N (3204 kgf).
The rear adjuster acts as a mechanical stop that shortens the effective stroke by up to 100 mm, creating a usable travel window of 175 to 275 mm. It allows precise end-position tuning at commissioning but does not lock the load without continuous air pressure.
